Earlier this year, we saw the addition of a fourth fuel option to the American Le Mans Series (ALMS) when it was announced that Dyson Racing would be running bio-butanol in its Lola-Mazda coupe.

This weekend's round of the American Le Mans Series at Miller Motorsports park in Utah will see the four Ferrari F430 GTs of Extreme Speed Motorsports and Risi Racing switch from running on an E10 ethanol/gasoline blend to using cellulosic E85. With this change, 10 of the 13 cars running in GT2 will be using the second-generation biofuel. The Corvette Racing team was the first to use E85 in early 2008 and since then the Flying Lizard Porsches and Rahal Letterman BMW M3s have also made the switch

The Dyson team ran one of its two cars unclassified as a test during the last two race
